react-navigation - 如何在 createMaterialTopTabNavigator react-navigation v4 上启用惰性？

Question

在 react-navigation v3 中，createMaterialTopTabNavigator有lazy选项，在 react-navigation v4 上，它仍然可用，但它不工作，根据github 帐户上的回复，似乎它只在 react-navigation v5 上再次工作。现在有人如何在 react-navigation-tabs 上启用延迟加载？

const CTabs = createMaterialTopTabNavigator(BTabs, {
  // Default config for all screens',
  initialRouteName: AScreen',
  tabBarComponent: Header,
  swipeEnabled: false,
  lazy: true,
  backBehavior: 'initialRoute',
});
